What if we rinse the syringe, which is used for transferring each solution into the test-tubes, with distilled water.will it affect the concentrations or results?
@@behlogy okayy no problemm . Take you time . But can you please make video on slides and microscope related practicals? Actually I have my practical exam next week and I'm sure your vids will be a great help.and thanks for your efforts ❤️❤️
Depends on: 1) What you need to get into uni! If uni just requires a B or C, it's good enough. 2) What grade you want in A2. A2 is wayyy harder than AS. So if your AS score is a B, do expect overall grade to be a B or even a C.
COVID exemptions are still in place and you can apply not to sit for paper 3. Personally though, I think paper 3 is the easiest paper to score and boost your grade with. All you need to do is to know all the rules to follow
Thank you so much!! I have my practical tomorrow morning and this was super helpful.
Thanks alot tomorrow my practical exam
My AS biology practical exam is tomorrow, thank you so much 🙏
thanks so much this is the most helpful p3 video ive every seen could never have done it without u❤
You are a lifesaver! Thank you so much for this series
hi
i have a small qs
time taken to reach end-point is the time taken for the first colour change or shall we wait till the colour turns brick-red
Depends on the question!
Are we allowed to use the same syringe for each of the concentrations
Yep. As long as the syringe touches stock solution, and nothing else. One syringe for water, one syringe for stock solution.
Hey do we have to decide the concentrations by ourselves ?
Most of the time!

Should be fine. But no time!
Do u have more videos of practicals?? Pleaseee telll
I'm working on it 🤣 they are way more time consuming than normal lectures!

How did it go? 🤔
Can someone tell me what 1 div of stage micrometer equals to?
it depends on your microscope. Refer to the how to use a microscope video to learn how to calculate it :)
Yeah this was really helpful
Is B a good AS score?
Depends on:
1) What you need to get into uni!
If uni just requires a B or C, it's good enough.
2) What grade you want in A2.
A2 is wayyy harder than AS. So if your AS score is a B, do expect overall grade to be a B or even a C.
So if I get a B in As its impossible to get a B or A in A2?
@@Bella-zj2sz it's possible but apparently it's really difficult. So resit for the exam if you don't get an A in my opinion
What if we start by the least concentration to most concentration with the same syringe to prevent contamination?
I think it's pretty much the same hahah
Is this the same as proportional dilutions??
Yes!
for paper 3 are the practicals compulsory?
COVID exemptions are still in place and you can apply not to sit for paper 3. Personally though, I think paper 3 is the easiest paper to score and boost your grade with. All you need to do is to know all the rules to follow
